EDWARD F. DREMAN, OF CLEVELAND, OHIO.

CUSHION-TIRED WHEEL.

Application filed January 16, 1917.

To all whom t may concern:

Be it known that I, EDWARD F. DREMAN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of GhiO, haveinvented a new and useful Cushion-Tired Wheel, of which the following isa speciication.

The device forming the subject matter of this application is a resilientwheel, and one object of the invention is to provide a wheel of thiskind in which spokes may be dispensed with, the wheel being of unusuallysolid and strong construction, so as to withstand the severe usage towhich devices of this type are subjected.

Another object of the invention is to provide novel means for supportingthe rimcarrying ring yieldingly for movement in a vertical plane.

Another' object of the invention is to provide novel means for guidingthe rim-carrying ring in its vertical movement.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the'above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in side elevation, a wheelconstructed in accordance with the present invention, parts being brokenaway; and

Fig. 2 is a transverse section taken approximately on the line 2 2 ofFig. 1.

In the accompanying drawing, the numeral 1 indicates an axle receiving ahub comprising tubular members 2 which abut at their inner ends adjacentthe median plane of the wheel, as indicated at 3. The hubs 2 may bekeyed as shown at 4 to the axle 1, although this detail is not insistedupon, the key 4 being omitted or used, depending upon whether the wheelis to run freely on the axle 1 or is to be driven thereby. The hubs 2,which preferably are made of metal, are supplied with integral sideplates 5 having thickened radial lugs 5a. Integral reinforceing ribs 6,projecting outwardly from the 'Specification of Letters Patent.

side plates 5, connect the side plates 5 with the hubs 2 and strengthenthe structure. Mounted between the side plates 5 is a resilient disk 7which embraces the inner ends of the hubs 2 closely, and fills the spacebetween the side plates. The disk 7 preferably is fashioned from rubber.Securing elements 8 pass through the lugs 5a of the side plates 5 andthrough the disk 7 near to the hubs 2, the side plates and the disk thusbeing bound securely together. One of the side plates 5 is supplied witha finger 9 which projects beyond the periphery of the side plate. Theresilient disk 7 is supplied with peripheral teeth 10. A ring 11 whichordinarily is made of metal, surrounds the resilient disk 7 closely andis slidable between the side plates 5, the ring 11 having teeth 12 onits inner edge which, interlocking with the teeth 10 of the resilientdisk 7, tend to prevent a creeping of the ring 11 circumferentially ofthe wheel. The ring 11 may have cavities as shown at 20, if desired, forthe sake of lightness. The ring l1 carries a rim 14 of any desiredconstruction, supporting a tire 15 which may be made as desired. Annularguide plates 16 are mounted on the opposite faces of the ring 11 andabut at their outer edges against the rim 14. The guide plates 16 areheld to the ring 11 by means of securing elements 17. The guide plates16 slide on the outer faces of the side plates 5 and prevent dirt fromgetting into the interior of the wheel, the guide plates 16 beingprovided with recesses 18 in which the outer edges of the side plates 5are adapted to `move. One of the guide plates 16 is provided withoutstanding lugs 19, located on opposite sides of the finger 9 whichconstitutes a part of one of the side plates 5. Should the teeth 10-12strip, wear out, or lose otherwise their interlocking engagement, thenthe finger 9, coperating with one of the lugs 19, will prevent the ring11 from creeping circumferentially of the wheel. Should the teeth 10 andl2 retain their hold upon each other, the resilient disk 7 yieldingcircumferentially, then the linger 9 will coperate with one of the lugs19 as above specified and for the purpose set forth.

In practical operation, the ring 11 carrying the rim 14 reciprocatesvertically, the resilient disk 7 yielding sufficiently to give thedesired result. The wheel forming the subject matter of this applicationwill be soV found to possess great strength, and to afford the necessaryresiliency in an exceedingly simple structure.

Having thus described the invention, what is claimed is In a device ofthe class described, a hub; side plates carried by the hub; a rim-ringslidable between the side plates toward and away from the hub; aresilient disk held between the side plates and extended inwardly to thehub, the disk and the rim-ring having interlocking' teeth whereby thedisk will constitute a means for cushioning` the circumferentialmovement of the rim-ring; and

spaced elements carried by the rim-ring and l5 determined eXtent and hascushioned the 2 circumferential movement of the ri1nring- In testimonythat l claim the foregoing as my own, I have hereto a'HiXed my signaturein the presence of two witnesses.
